RAILROAD-GATE.

E-LPECIFICATION forming part of Letters Patent No. 331,333, dated December 1, 1885.

Application filed December 10, 1884. Serial No. 150,047. (No model.)

To all whom it may concern:

Be it known that we, CORNELIUS S. RIGGIN and ALBERT E. GUMMERSON, citizens of the United States, residing in Newark, Essex county, New J ersey, have invented certain new and useful Improvements in Railroad Safety-Gates, fully described and represented in the following specification and the accompanying drawings,forming a part of the same.

This invention consists in the combination, with the gate, of oscillating arms mounted upon shafts above the opposite ends of the gate, connections from the arms to the gate, pulleys connected with the arms to actuate them simultaneously, crossed ropes applied to the pulleys to operate them in different directions, a hand-lever, and a connection from the hand-lever to the pulleys for oscillating the pulleys by the vibrations of the lever; and it also consists in a modification thereof, including counterbalanceweights.

In the drawings, Figure 1 is an elevation of a pair of gates having the hand-lever connected with the vibrating arms and wheels by rods and cranks. Fig. 2 is an end elevation 'of a pair of gates, and 3 is a plan of the same.

A is the gate, fitted to slide in grooved posts B, and E are the lifting-arms secured upon shafts F at the tops of the posts B. These arms are coupled to the gate by links G, and are secured to the shaft F, so as to turn with the pulleys G, the pulleys being so connected as to turn in opposite directions by means of crossed ropes H, which have their ends securely attached to the rims of the pulleys. The arms both point in toward the middle of the gate, and serve to raise the ends of the gate equally when either of the pulleys G is rotated a sufficient distance, as one-third or one-fourth of a circle, depending upon the length of the arms E and the rise required for the gate.

The gates are counter-balanced by weights 0, which are hung to cords 0, attached to the rims of the pulleys G, so as to be lowered or raised when the gate is raised or lowered by means of the pulleys G.

I is the hand-lever; I, a crank affixed thereto, and J a multiplying-lever above the lever I upon the pest B.

J are rods connecting the crank I with the lever J and with a crank, K, affixed to the upper pulley, G, so that the vibration of the hand-lever produces the required oscillation of the pulley G and arm E by a single movement on the part. of the operator. By the balancing of the gate and the connection of the liftingarm with the hand-lever I, in the manner described, we are thus able to effect the desired movement in the gate very rapidly and easily.

From the above it will be seen that the combination of the arms E with the pulleys G, connected together by the cords or ropes H, so as to turn simultaneously, affords a means of raising the two ends of the gate by a partial rotation of the pulleys G, and thus enables us to operate the gate by a single movement of a hand-lever.

YVe are aware of the state of the art shown in United States Patents Nos. 218,551, 121,654, 214,319, and 162,576, and Reissue No. 16 4:, some of which show that it is not new to use a counterbalance-weight or a lever to raise the gate by a connection thereto, but our invention differs from former constructions in the combination, with the pulleys G, of the liftingarms E and connections to the weights 0, by which construction we secure the advantages just described.

We therefore disclaim the said patents, and claim our construction as follows:

1. The combination, with the gate A, of the oscillating arms E, mounted upon shafts above the opposite ends of the gate, the connections G from the arms to the gate, the opposite pulleys G, connected to the arms to actuate them simultaneously, the crossed ropes II, applied to the pulleys, a hand-lever, and a connection from the hand-lever to the pulley for oscillating one of the pulleys G by the vibration of the lever, the whole arranged and operating substantially as and for the purpose set forth.

2. The combination, with the gate A, the arms E, connections G, oscillating pulleys G, and ropes H, arranged and operated as herein shown and described, of the counterbalance-weights O, suspended from the rims of the pulleys G by ropes G, substantially as and for the purpose set forth.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.

CORNELIUS S. BIGGIN.

ALBERT E. GUMMERSON.
